What is Denso on a O2 sensor?
Denso oxygen sensors feature an aluminum-oxide trap layer to protect the ceramic from silicone and lead poisoning, preventing damage to the platinum electrode. Double protection cover maintains proper unit temperature for quicker response times and protects the ceramic element from contamination.
How long do Denso O2 sensors last?
Even still, the lifespan of a modern O2 sensor may be 60,000 to 90,000 miles. Cars with bad O2 sensors will activate a check-engine light and may idle rough and get poor fuel mileage because they’re operating in “open loop” to a pre-determined fuel map.

What does a bad air fuel ratio sensor do?
The air-fuel ratio sensor monitors the oxygen content in the exhaust stream and sends data to the computer so that it can add or subtract fuel. If there is any problem with the sensor, it can send a bad or false signal to the computer which can throw off its calculations and cause it to waste fuel excessively.
